yeah,bcoz it moves in circle around a specific point.
Angular momentum is used in various applications in physics and engineering, such as in analyzing the motion of objects in rotation (like spinning tops or satellites), understanding the behavior of gyroscopes, and explaining phenomena like the conservation of angular momentum in celestial bodies. It is also crucial in quantum mechanics for describing the rotational properties of particles.
Wf - Wi = a*t, where Wi and Wf are the initial and final angular velocities, respectively, a is the angular acceleration, and t is time. So, a*t = 15.4 rad/s - 8.5 rad/s = 6.9 rad/s, thus a = 6.9 rad/s / 5.2 s = 1.3 rad/s2.
A four-blade fan typically moves more air than a two-blade fan because it has more surface area to push the air. This allows the four-blade fan to generate more airflow with each rotation compared to a two-blade fan.
To calculate the force on the fan blade, we first convert the weight from ounces to pounds (3 ounces = 0.1875 pounds). Then, we use the formula: force (in pounds) = weight (in pounds) x radius (in feet) x angular velocity squared (in rad/s). Given the radius of 15 inches (convert to feet by dividing by 12), and an angular velocity of 900 rpm (convert to rad/s by multiplying by 2π/60), we can calculate the force on the fan blade.
This phenomenon is due to inertia, where the blades of the fan will continue to spin briefly after the fan is turned off until the force causing them to move is dissipated. The air resistance and momentum of the spinning blades contribute to this delayed stopping effect.

The blade will go off if the electric fan is turned off.
six blades of a fan divide 360 degrees into six segments. each angular segment therefore is of 60 degrees each. So angle between blades of a 6 blade fan is 60 degrees.
The kinetic energy of the fan blade will decrease to one ninth of its original value because kinetic energy is proportional to the square of the angular velocity. So, if the angular velocity is reduced to one third, the kinetic energy will decrease to (1/3)^2 = 1/9 of its original value.
Wf - Wi = a*t, where Wi and Wf are the initial and final angular velocities, respectively, a is the angular acceleration, and t is time. So, a*t = 15.4 rad/s - 8.5 rad/s = 6.9 rad/s, thus a = 6.9 rad/s / 5.2 s = 1.3 rad/s2.
A: That will be true ONLY if the blades have a pitch to it
The noise coming from the bathroom fan when it is turned off could be caused by a loose or damaged fan blade, motor, or mounting bracket. It is recommended to have a professional inspect and repair the fan to prevent further damage.

By causing it to rotate a fan or blade of some sort that is conected to a generator which in turn gives out an electric curent.
many times it'd the run capacitor (that cylinder) where the wires from the fan run. if the fan is turned on and you hear a hum, tap the blade. if the fan turns, then that's the problem.
